Save Money with An Efficient Economizer

We work hard to make sure you get the most out of a preventive maintenance agreement with Yale Mechanical. This saves you money in a variety of ways, including lower energy costs.

One way to lower your energy costs this spring is with an efficient economizer. Just like opening a window in your home, the economizer draws cool air into your building when outside temperatures are favorable. The end result is free cooling for your building, but only when it’s working properly. As part of our preventive maintenance program, our qualified technicians inspect the following controls:
